can-noon.

To all whom it may concern:

Be it known that I, THOMAS NATHAN RUssELn, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gar-Roofs, of which the following is a specification.

The invention relates to outside metal car roofs, and more particularly, and prin cipally, to the means for securlngthe roof sheets at-the eaves, consisting of an improved form of clip for the sheet metal seam of such roof sheet. The invention comprises the parts and combinations thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood, there are shown in the accompanying drawings means for carrying the sameinto practical effect without limiting my improvements, in their useful applications, to the particular construction which, for the purpose of example, has been delineated.

In said drawings:-

Figure 1 is a vertical transverse section of a portion of a car roof, comprising the seam clip in position to'movably secure the roof sheets, the clip beingin section on line II of Fig. 2. a

Fig. 2 is an outside elevation of the seam clip.

Fig. 8 is an elevation of the same looking longitudinally of the car.

Fig. at is an inside elevation of the same.

Fig. 5 is a transverse sectionalview of one form of roof sheet seam to which the said clip is applicable.

Referring to the drawings, 1 indicates a side plate, 2 the side sheathing, 3 the top sheathing, 22 a side fascia and 23 the roof sheets, the latter being formed along their sides with interlocking inverted V-flanges (Fig. 4) from the ridge to the caves of the roof. The fascia is secured by nails 8 and bolts 9, the latter passing through the side plates.

10 is the seam clip made as a one-piece malleable casting, and formed with a hood 11 which incloses the outer ends of the said roof sheet seam flanges. The side walls of this hood are at their lower edges extended horizontally away from the seam to form tongues 12 which fit loosely upon the top surfaces of the eaves ends of the roof sheets Specification of Letters Patent.

to hold them down in place, but allow any necessary horizontal movement. Between these tongues andthe top part of the hood the side walls of the latter are formed with openings 13,t0 allow of the escape of some cinders and dust and'the dryingout of mois ture. The clip is also formed with a central attaching leg 14 which unites with the end wall 15 of the hood. The upper part 16 of this legclosesthe otherwise open end of the roof sheet seam, and is formed with a recess 17 in which are received the depend ing eaves flanges27 of the flashing. The leg is also perforated with a bolt hole 19, and anail hole 20 in its'lower extremity in whichmay be received certain of the said securing bolts 9 and nails 8, respectively.

At the sides of the leglthe endwall 15 of' the hood is'upwardly recessed so as to form end openings 21 above the plane of the top of the roof for the freeescape of water, cinders and dust which would otherwise be collected and confined, and which would cause rusting out of parts of the roof sheets and the subsequent rotting of the wooden parts below.

The leg 14 is extended above the edge of the roof and thence outward to form the said escape openings 21 at each side of the leg, and it is thence extended farther and laterally to merge with theouter ends of the said confiningtongues'. This construction' gives great strength to'the' clip, provides an efficient securing of the roof sheet seams togetherwith' ample room for lateral play of the same (see Fig. 4:) and is very useful in prolonging the life of the roof sheet by allowing a free escape of cinders and drainage through the openings 21, which would otherwise cause a rapid rusting and deterioration of the roof sheet elements near their eaves portions.

The described clip is very readily attachable, with the minimum of work, in assembling the roof; it confines the sheet scam in forward and rearward directions, but loosely; and holds down the eaves ends of the sheets but so as to allow them to have horizontal play. By its central leg it closes the outer end of the seam, and at the same time allows the escape of water and cinders at the sides of the seam and leg through the openings 21.

The side fascia 22 is shown as a single element applied directly against the side sheathing. The roof sheet 23 terminates over the fascia in a downward bend 24: from which an inturned flange 25 extends under and parallel with the main body of the sheet. 26 is an eaves flashing in the form of an angle plate, the vertical member 27 of which incloses the top part of the outer side of the fascia 22 and is secured thereto by nails 28. The other angle member 29 extends inward over the said fascia and beyond the inner face thereof, lying below the roof sheet flanges 25, which latter are shiftable on and over the member 29. 30 is an eaves strip or hook-stripping of gooseneck or T-form in cross section, having a vertical flange 31 which incloses the outer edge of the top sheathing and is confined beneath the fascia. It is secured to the side sheathing and side plate by nails 32. At the upper end of the flange31 the eaves strip is bent inward and then outward, forming lower and upper parallel flanges 33, 34:, which include between them the inner edge of the flashing member 29. The upper eaves strip flange 34 enters between the roof sheet and its flange 25. The fascia is secured to the side plate by the through bolt 9.

The seam which joins the sides of the roof sheets is formed by side flanges of the sheets, which flanges may be termed rights and lefts, the two flanges of each sheet being of different arrangement so that the flange of one sheet incloses the differently arranged flange of the contiguous sheet, and the seam is formed above one of the sheets (Fig. 5). The two said flanges are of substantially inverted V or U-form. The outer or inclosing flange 35 extends beyond the body of the sheet, and has a terminal upwardly and inwardly bent lip 36 which reenters within the inner flange of the next sheet. The said inner or inclosed flange is shown at 37 and it is bent to overhang the sheet on which it is formed. The outer end of this seam is embraced by the hood 11 of the seam clip 10, and the open end of the seam is opposed by the central leg portion 16.

The side sheathing is carried up at the outside of the top sheathing and stops short of the top of the latter and the top of the side fascia is substantially level with the top of the side sheathing, so that a recess is provided for the eaves strip and eaves flashing without rabbeting the outer edge of the top sheathing.

The clip may be applied to a seam of the character shown in dotted lines in Fig. 4, in which both of the seam flanges extend up and away from the body of the sheet.

This application is a division of my application Serial No. 822,258, filed March 4, 1914;.

What is claimed is:

A seam clip for car roofs, comprising a central vertical leg or shank adapted to be attached to the side of a car, the said shank being extended upward to closely confine the flashing and farther upward to form an end closure for the roof sheet seam, said closure extending laterally and being formed with a central widened hood member and with inwardly extending and roof sheet confining tongues at the lower sides of said hood, the said leg being extended above the edge of the roof and thence outward to form drainage and dust escape openings 21 at the sides of the leg, and thence being extended to laterally merge with the outer ends of said confining tongues;

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
